Learn when and how to wean Kunekune piglets, what readiness looks like, how to reduce stress, when BF Farm introduces solid feed, and what to watch after separation.
Weaning should be a transition, not a surprise. By the time I separate a Kunekune litter from the sow, I want the piglets already eating well, drinking confidently and comfortable with the feed, pen mates and daily routine they will have after separation.
At BF Farm I usually prefer weaning closer to about eight weeks when the sow is maintaining condition and the litter is thriving. That is a farm-management preference, not a rule that every healthy Kunekune litter must follow on the same day.
There Is No Single Kunekune Weaning Day
Published swine guidance covers a wide range of weaning ages because management systems are different. Veterinary guidance describes natural sow-led weaning as much later than commercial weaning, while small-farm systems often keep piglets on the sow longer. [1]
I care more about readiness than forcing a litter to match a date on the calendar.
Solid Food Starts Well Before Weaning

I begin introducing piglet-appropriate feed at about two to three weeks while the piglets are still nursing. At first they may investigate more than they eat. That is fine. The point is to make solid feed familiar before milk disappears from the routine.
If you are at that stage now, use the BF Farm guide to introducing food at about two to three weeks.
Piglets may begin investigating solid food before they are ready to leave the sow. The Kunekune feeding guide helps distinguish early feed introduction from meeting the nutritional needs of a growing, fully weaned piglet.
What I Want to See Before Separation
Readiness matters more than a calendar date
Healthy + gaining
Piglets are active and continuing to grow.
Eating solid feed
They consistently eat an appropriate complete starter or grower ration.
Using clean water
They already know where the water is and drink independently.
Sow + litter ready
The separation is planned, not an emergency response to a struggling piglet.
If one of these pieces is missing, age by itself does not make the piglet ready.
- Piglets are healthy, active and gaining.
- They are eating an appropriate complete starter or grower ration consistently.
- They know how to find and use clean drinking water.
- They are comfortable with their littermates and normal daily handling.
- The sow is healthy enough for a normal, planned separation rather than an emergency removal.
A piglet that is technically old enough but not eating well is not ready just because the calendar says so.
Instead of relying only on a calendar date, watch that piglet's appetite, growth, activity, and condition. The body-condition guide explains the principles of condition assessment while young pigs continue developing.
Keep Weaning Boring

Weaning already changes the piglet's social and nutritional world. I try not to pile several other major changes on top of it.
Avoid combining a big feed change, unfamiliar pen, and new social group on the same day if they can be staged. The herd-introduction guide offers additional ideas for introductions and watching resource competition.
- If practical, keep the piglets in familiar surroundings and move the sow.
- Keep the same feed and water system through the first days after separation.
- Keep littermates together when that fits the management plan.
- Avoid an abrupt feed change at the same time as separation.
- Watch appetite, manure, hydration, behavior and body condition closely.
Watch the Sow Too
Weaning is a change for the sow as well. Milk production has to decline, so I watch the udder and the sow's overall comfort after separation. Marked heat, swelling, pain, fever, poor appetite or illness deserves veterinary attention.
When Earlier Weaning May Be Necessary
Sometimes the management plan has to change. Earlier separation may be appropriate if the sow is losing excessive condition, the sow or litter has a health problem, there is an injury or safety concern, milk production is inadequate, or a veterinarian recommends a different approach.
Those are individual-animal decisions. I would not turn an emergency exception into a routine target for every litter.
Illness, poor growth, or a sow that cannot nurse may require individual veterinary advice. Use the when-to-call-the-vet guide to recognize other warning signs rather than trying to solve every difficulty by changing the weaning date.
What About Fermented or Wet Feed?
I may use soaked or fermented feed as one way to make solid feed interesting to piglets, but it is not required for successful weaning. A complete, age-appropriate ration and clean water matter more than whether the feed is dry, freshly wetted or intentionally fermented.
If feed is fermented, sanitation and a controlled process matter. “It smells sour” is not a food-safety test.
Fencing Is a Separate Subject
Weaning and fence training do not need to happen as one event. BF Farm does not use hot-wire training as part of my own herd routine, so I do not present electric-fence training as firsthand BF Farm husbandry.
Owners who choose electric fencing should use appropriate fencing guidance and train pigs safely inside a secure physical perimeter before depending on an electric strand as the primary boundary. That is a fencing decision, not the definition of weaning.
A pen suitable for adults may still have gaps a small piglet can find. The fencing guide discusses gate and perimeter design; the actual piglet pen must be checked at piglet height.
The First Days After Weaning
I want weaned piglets to settle into a predictable rhythm: eat, drink, rest, move normally and stay interested in their surroundings. A short adjustment period is expected. A piglet that stops eating, develops persistent diarrhea, becomes dehydrated, isolates itself or loses condition needs attention.
Keep feed fresh, water easy to find, shelter dry and the social group stable. This is one of those times when boring management is good management.
BF Farm's Weaning Sequence
From nursing to planned separation
Birth–72 hours
Warmth, colostrum, nursing and close observation.
First ~2 weeks
Litter remains separately managed through identification, tagging and microchipping.
About 2–3 weeks
Introduce piglet-appropriate solid feed while nursing continues.
Following weeks
Build confident feed and water intake; watch growth and body condition.
Closer to ~8 weeks
When sow and litter are doing well, make the planned weaning transition.
- Birth through the first 72 hours: warmth, colostrum, nursing and close observation.
- Roughly the first two weeks: separately managed litter through identification, tagging and microchipping.
- About two to three weeks: begin introducing piglet-appropriate solid feed while nursing continues.
- Following weeks: build confident feed and water intake and watch growth and body condition.
- Closer to about eight weeks when sow and litter are doing well: make the planned weaning transition.
For the beginning of that sequence, see the Kunekune farrowing and newborn piglet care guide.

About the Author
Mark Bengtson manages BF Farm piglets from birth through weaning. His current practice is to introduce solid feed at about two to three weeks and, when sow and litter are doing well, generally prefer a later weaning closer to about eight weeks. BF Farm does not use hot-wire training as its own husbandry routine; fencing guidance is intentionally kept separate from the weaning process.
